Everyone had roughly the same results but completely different means of getting those results. Before I go onto the winning solution I would like to go over some of the solutions I did not chose and brief reasons why.
Here is one email:
It is easy to tell by the rendering that the results are decent and look nice. The only problem I have with this solution is managing two light fixtures. If you move the light fixture with the geometry it will not reflect in that scene until you move the other light fixture.
One last solution before the winner:
This is most certainly a workaround of sorts and i encourage all of you to experiment with this option because the results are very nice. The problem is that you will not have any of the artificial lighting effects correct. The questions specifically asks for artificial lighting. Although the look may be the same there will be no task lighting, effect lighting, spot lighting, etc...
Now.... the winner of the first ever Revit Kid Challenge is....
Eric Stewart!
I will simply replicate his email because it was that good:
I have a solution but it may not be the best.
"I modeled a simple two room plan. In one room I have a wood floor and in the other a tile floor. I placed the "Ceiling Light - Flat Round.rfa" in several places. However, as it is out of the box, the family will display in the renderings, which is the problem to begin with. So I edited the family and added a new object style to "Lighting Fixtures" called "Fixture."
For each of the objects defining the fixture I changed its object style to my newly created style. Once reloaded in the project make sure that subcategory is turned off.
Looking forward to other answers/solutions."
This solution is the route that I would have taken to solve this problem. Using the power of the program and ability to turn objects off without having to create new separate entities is key. Now the rendering will update when you change the reflected ceiling plan or anytime you make any change to the fixture.
Congratulations Eric and please email me your information so I can send you your very own Revit Kit t-shirt.
